in my book there are three super villians that control sound powers.
voculst: a rock n roll vampire that wields the all mighty guitar weapon sound slave. he's crafty and very fast and his minnion of choice... night ravers a type of demon whos body lights up like a glowstick that wield glow stick like glowing energy weapons.
beat master: a dj themed villian that summons four giant levatating speakers to aid him in battle that can deflect attacks or pound his opponent with solidified sound waves.
platinum diva: the third member who chose to bounty hunt rather than be a criminal. she can use sound to travel so fast that her enemies are often caught off guard. her armor which is powered by a spinning platinum record deflects magic and absorbs basic physical attacks.
